Jem - Season 2 Episode 14 The Princess and the Singer

Loosely based on the Mark Twain story The Prince and the Pauper, while touring the small European country of Morvania, Kimber meets Princess Adriana, the teenage heir to the throne who happens to look exactly like her. When Adriana escapes from her room, her power-hungry cousin Lexa hires her henchmen to track her down and bring her back. When Kimber and Adriana bump into each other, Lexa's henchmen discover Kimber (Who they think is Adriana) then kidnap her and lock her in a tower where she escapes. Lexa discovers that the real Adriana is with the Holograms so she uses the Misfits to lure Kimber to the hotel where the Holograms are staying and plant a bomb on the stage (to kill Adriana) and take over the throne. The Misfits gatecrash the party and save the Holograms from the bomb on the stage. The Holograms then rescue Kimber, Lexa is placed under arrest for conspiracy, and Adriana claims the title of crowned queen at last.
